JASPER, NEV YORK.

IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 43.423, dated July 5, 1864.

T0 a/ZZ whom it may concern.-

Beit known that l, ROBERT MURPHY, of Jasper, in the county ot' Steuben and State of New York, have inventeda new and Improved Churn; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable any person skilled inthe art to make and use the same, reference being had to the accompanying drawings,

Figure l is an external view of my invention 5 Fig. 2, a vertical central secti n of my invention, taken in the liner x, Fig. l.

Similar letters` of reference indicate the same parts. i

This invention consists in suspending a barrel-shaped cream receptacle on transverse trunnions in a suitable framing', in combination with the application ot' weights or coun teipoises to the receptacle for the purpose of acting as a iiywbcel, and by their momentum insuring a uniform or steady rotation ot' the receptacle, as hereinafter described.

A represents a barrel-shaped cream recep tacle, provided with a `journal or` trunnion, a, at two opposite points at its center, said journais or trunnions being fitted in bearings b on a framing, B. One of these journals or trunnions a is provided with a crank, c, for the purpose of turning the receptacle'.

The cream-receptacle is provided with an arm, d, at two opposite points, said arms being in a plane at right angles to the plane of the journals or trunnions a (t. These armsi have a weight or counterpoise, (ZX, at their outer ends, which serve to keep the receptacle in a state of equipoise and insure a steady or uniform rotation ot' the same by compensating for the elongated shape of the receptacle,

ceptacle, one-half of the hoop being on the main portion ofthe receptacle, and the other halt encompassing the lid, as shown cle: r y in Fig. 2. The lid is rmly secured to the body or main portion of the receptacle by means of hooks LX and staples b", as shonn in both figures.

The bu :ter is produced very expeditiously by rotating,` the receptacle A, the elongated form ofthe latter, in connection with its revolving movement, producing the necessary agitation of the cream to eit'ect that result.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A barrel churn, A, rotated upon transverse trunnions aa, and provided with coun terpoises dX (1.x, the whole being ananged to operate in the manner and for the purpose set forth.

ROBERT MURPHY.
